Abstract

Devices for affixing sutures, grafts and tissues to bone, and soft tissue such as periosteum. In a first embodiment, the invention comprises a piton member implantable within bone having a post or eyelet formed thereon to which the suture or tissue may be attached. The piton member is designed to become more firmly secured within the bone when pressure is applied to a first axis pushing the piton member into the bone, but may be easily removed when such force is applied in a generally opposed direction. In a second embodiment, the invention comprises affixation devices that are designed to detachably ensnare with periosteum. Such devices are provided with attachment structures, such as one post, eyelet or other means for securing sutures, grafts, synthetic materials or tissues.

Claims2

Dependent claims

A surgical implant for securing sutures, graphs, synthetic materials, in soft tissue to bone or soft tissue at a selected target site comprising:

a) a piton member formed from non-bioabsorbable material having proximal and distal ends, said distal end comprising at least two opposed outwardly-flaring prongs for piercing directly through in thereafter becoming embedded within said bone or soft tissue such that each respective one of said prongs defines a dedicated pathway of penetration therewithin:
b) an attachment member formed upon said proximal end of said piton member, said attachment member being formed from non-bioabsorbable material and designed to receive and securably hold said suture, graph or soft tissue such that a strain is imparted thereto;
c) wherein said attachment member is formed relative said piton member such that in use, when said suture, graph or soft tissue is attached to said attachment member and tension is applied thereto, such strain is imparted about a first axis and said prongs of said piton member are caused to advance towards said dedicated pathways of penetration;
and
d) wherein said dedicated pathways of penetration and said first axis are not parallel to one another.
